I was searching for something along these lines. I have two dropdown fields on my form which are cascading menus pulling from SharePoint lists. When a user selects an option in dropdown A, the corresponding values in dropdown B show. This works well. However, if they choose a corresponding value in dropdown B and decide to change dropdown A to another value, the new values in B are displayed, but the old value they selected in B previously to the change is also displayed. Is there a way to clear this value for dropdown B and only show the corresponding ones for B based on the change from A, to ensure more accurate data entry.
